Pleated seal for surgical hand or instrument access
First Claim
1. A hand or instrument access assembly comprising:
- a housing; and
a seal body mounted to the housing, the seal body having a first proximal surface and a second distal surface opposing the first proximal surface, the seal body defining a substantially centrally disposed opening extending through the first proximal surface and the second distal surface, and second openings for sealed reception of an instrument therethrough;
the first proximal surface having a plurality of first channels extending radially outwardly from the substantially centrally disposed opening and coterminous therewith and the second distal surface having a plurality of second channels extending radially outwardly from the substantially centrally disposed opening and coterminous therewith, the plurality of first channels being radially offset relative to the plurality of second channels, wherein the plurality of first and second channels are separate and distinctly formed from one another, at least one of the second openings being positioned in between at least two of the first channels of the plurality of first channels.

Abstract
A surgical access assembly for a surgical instrument and/or a surgeon'"'"'s hand, the assembly including a housing, such as a wound retractor, and a seal body mounted to the housing. The seal body may have a pleated configuration when viewed in cross-section. The seal body may have a first surface and a second surface, the first surface having a plurality of radially-extending first channels and the second surface having a plurality of radially-extending second channels, the plurality of first channels being offset from the plurality of second channels. The seal body may define a substantially centrally disposed opening for reception of a hand/arm or instrument. In addition, the seal body may define one or more additional openings for simultaneous reception of an instrument and a hand.
